Arduino IDE won't open on macOS Mojave

I can't get the IDE to open at all. I tried deleting the installed version and downloading an update but it still won't open. It starts to open then disappears.

Ideas welcome please

Which version of the Arduino IDE are you using?

Are you using Teensyduino?

There is a similar issue, but it only affects macOS versions older than 10.12 and I see that Mojave's version is 10.14, so that indicates your problem is something else.

I'm having similar problems and only a restart seems to cure it.

Hi every body.

arnaudb12: I cannot install IDE

Please provide a detailed description of what you mean by "cannot install IDE". If you are getting any error messages, post the full and exact text of the error message.

I was trying to accomplish install via but to no avail. I read a lot of forums like this but it didn't help.

My suggestion is to skip their download/install completely and install homebrew and install arduino from there instead. Completely without aches.

Install homebrew from here:

Install using homebrew in your terminal by typing this: brew cask install arduino

Happy coding
